` Specification of Letters Patent.

Application led August 10, 1915 Serial No. 44,827.

To all whom t may concern:

Be it known that I, WINKCENTY KRAGIEL,

a subject of the Czar of Russia, and resident e of Norwalk, in thecounty of Fairfield and State of Connecticut, have invented certain newand useful Improvements in Locks, of which the following is aspecification. 'Y

' This invention relates to locks and latches and particularly toautomatically timed controlled locks associated with novel means foropenin the lock at a predetermined time.

An o ject of this inventionV is to provide a' door with latches intendedto hold the door` in closed position, said latches being automaticallyactuated to cause the said latches to interlock with the 'door j amb,safe structure or the like, mechanism being provided for `actuating thesaid latches to unlock the same and novel means being -provided wherebya clock or timing mechanism communicatesmotion to the llatch actuatingmechanism for withdrawingthelatches and unlocking the door. A furthervobject of this invention is to provideV novel means for mounting theclock or timing mecha'-Y nism with relation to the door and the operatinparts ofthe latches.v y

lVth the foregoing andother objects in view, theinvention consists inthe details of construction, and in the arrangement'and combination ofparts to be hereinafter more fully set forth and claimed.

f In ydescribing the invention indetail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote correspond-V ing parts in the several views, and inVwhichf Figurey 1 illustrates a view in elevation of a fragment 4of 'theinterior of-a door with the'invention applied thereto; j

Fig. 2 illustrates a -view similar toFig. l showing. the latch actuatingmechanism in position vwith the latches withdrawn;

Fig. 6 illustrates 'a sectionall view on the line 5 -5'0f Fig. 1, withthe timing mechanism in' a different position of adjustment g withrelation to the lock actuating means;

Fig. 7 illustrates` a perspective. view of' a;

cam for moving the lock actuating mechanism;

Figs. 8 and 9 are perspective views of fragments of ka shaft with thelugs thereon; an

In these drawings 15 denotes a fragment 0f a door havin guides 16 inwhichfthe latches 17 are slldable. Each` latch` has a shank 18 and anextension 19 which is slidable in a bracket 2O and at the junction of`the shank and extension, there is a flange 21 against which a latchoperating arm 22 works for the purpose of retractingy the latch againstthe action of a spring 23 which spring encircles the extension and isinter` posed between the bracket 20 and the flange 21. The function ofthe spring is to press the latch normally outward and to hold it inPatented oct. s, 191s.

Figs. 10, l1 and 12 illustrate perspective'y l locked position and thefunction ofthe arm 22 is to retract the said latch. j

It is to be understood that a plurality of latches may be employed butthe foregoing description of the latch and itsk associated parts willsuffice as a description-of thel carried by the door and said shaft hasa plurality of cam lugs 25 for a purpose to be presently explained. Theupper portion ofl Ithe shaft 24 has a lug 26'engaged by a bolt 27 ywhichis slidable in the guide 28 secured to the door and the bolt is heldnormally Y projected by a spring 29 which encircles the y bolti 27between a guide bracket30 anda shoulder 31 formed on the bolt.` Theinner end'of thebolt has a shoulder 32lwhich` is engaged by a lug 33 onavrock shaftx34 which is journaled in the door 15 the said rock shaftbeing operatedby a ypinj35 which slides vertically in the guide andisada'pted to bear against a lug`36 projecting from 'the' rockshaft, thesaid lug 36 being at van angle with relation to the lug 33. yWhenpressure is applied to the pin 35, its head bearsagainst the lug 36 andmoves the rockkshaft and the. said lug 33 which is'in engagement withthe shoulder 32 Lof lthe bolt causes a movement of the boltlongitudinally of the uide, thus withdrawing the projecting end of thesaid bolt from the lug on the shaft and releasing/the-'said shaft,permitting the latches of the door to 'be forced" into locked positionby the mechanism heretofore eicplained.

As a means for operating the shaft 24: at

predetermined times, timing mechanism isil employed, the said timingmechanism beingwith a ca-mmingvblock' il which engages thev Vhen the camlug 25 on the said shaft. ala-rm. mechanism 1s set for `a certain.l hourand the"v alarm goes-off. the alaian'nvindin-g.
